Premium double-sided VHB foam tape with 120 mil acrylic adhesive core, offering superior bonding strength, immediate handling, and long-term durability for industrial applications across transportation, electronics, appliances, and signage.
3M™ VHB™ Tape 4959 is a premium double-sided foam tape engineered with a general-purpose acrylic adhesive and a firm acrylic foam core, delivering a total thickness of 120 mil (3.0 mm). This industrial-grade bonding solution offers immediate handling strength without requiring fixturing or curing time, making it an ideal alternative to traditional mechanical fasteners such as rivets, welds, and screws. The tape's advanced closed-cell acrylic chemistry provides exceptional adhesion to a broad range of high surface energy substrates including metals, glass, aluminum, stainless steel, galvanized steel, composites, plastics, acrylic, polycarbonate, ABS, and painted or sealed wood and concrete.
Designed for long-term durability and reliability, 3M™ VHB™ Tape 4959 delivers high shear strength and reliable surface adhesion while maintaining excellent indoor and outdoor performance. The tape performs in short-term applications at temperatures up to 400°F (204°C) and long-term use up to 300°F (149°C), making it suitable for extreme environmental conditions. Its viscoelastic acrylic foam provides unique energy-absorbing and stress-relaxing properties, offering superior vibration and fatigue resistance that traditional fastening methods cannot match.
This versatile bonding tape excels across multiple industries including transportation, signage, displays, general industrial, appliance, and electronics manufacturing. With its ability to join thin, lightweight, and dissimilar materials while maintaining a smooth, seamless appearance, 3M™ VHB™ Tape 4959 eliminates the need for drilling, welding, grinding, and cleanup. The tape's excellent solvent and moisture resistance, combined with its UV and temperature stability, ensures consistent bonding performance from extreme heat to extreme cold. Each case contains 18 rolls, with each roll measuring 1/2 inch wide by 36 yards long, providing comprehensive coverage for industrial bonding and sealing applications.
